Question

我今天将Flutter升级到了v1.12.13版，但是当我运行该应用程序时，出现以下错误-

Compiler message:

我正在使用CachedNetworkImageProvider的最新版本。

Answer 1

当前看起来像是活跃的issue。将版本更改为2.0.0-rc可暂时修复该错误。

Answer 2

如official page

中所述

在Flutter 1.10中使用ImageProvider.load进行更改

Flutter团队对Flutter 1.10.15（当前仅适用于主渠道）中的ImageProvider进行了重大更改。

如果遇到以下错误之一，请升级到2.0.0-rc。

切换到cached_network_image: ^2.0.0-rc

如果问题仍然存在，请尝试flutter clean并运行。

升级到最新的Flutter Stable版本后，CachedNetworkImage引发错误
